Ohh tried to do some preventive maintenace on my motorcycle by changing the spark plugs. Well I ripped one plug boot trying to get if out. Then could not figure out how to get the wire out so I pullit it out of the coil. Went to the dealer and found out that the boots unscrew from the wire and are not supposed to come out of the coil. Saved an $80 part and had to buy a new $139 one. Plus they are special order so it takes a week to get them. Ugggghh!!!
